Notes : 1. QUASI SPLIT SOUND CHANNEL

Video carrier relative level = 0dB

f = 38.9MHz

∆f = 0 Sound carrier relative level = 13dB (mono or L) f = 33.4MHz

Sound carrier relative level = -20dB (R)

f = 33.16MHz

VI = 10mV Video carrier modulated with syncs ; V22 = 2V, unless otherwise specified.

2. FRENCH SOUND CHANNEL

VI = 10mV (Carrier level) ; fo = 39.2MHz ; Fm = 1kHz ; m = 80% ; V22 = 0.8V, unless otherwise specified.
